APPARATUS FOR DISPLAYING ADVERTISEMENTS.

SPECFICATION forming part of Letters Patent No. 442,274, dated December 9, 1890.

Application tiled August 2,1890. Serial No. 360,757. (No model.)

To all whom it may concern:

Be it known that I, CARL OTTO RADDE, merchant, of the city of lIamburg,in the German Empire, have invented a new and useful Improvement in Apparatus for Exhibiting' Advertisements, of which the following is a specification, reference being had to the accompanying drawings.

This invention consists in the apparatus hereinafter described and claimed for exhibiting advertisements in which a high upright frame covered with the advertisements, pictures, the., to be exhibited is brought into intermittent rotary motion for exhibiting the advertisements in an effective manner.

The apparatus is representedin its main features in the accompanying drawings.

Figure l. represents a side elevation of the frame with its bearings and motor. Fig. 2 is a view at right angles to Fig. l of one-half of one of the mounts. Fig. 3 is a front elevation of the motor with the disengaging device for the intermittent motion of the frame. Figet shows another position of the disengaging mechanism, and Fig. 5 is a plan of the frame.

Similar letters of reference designate corresponding parts in all the figures.

The whole apparatus is mounted on a frame which is constructed weather-proof, being provided with large panes of glass for showing the apparatus within and illuminated by electric or gas light. rlhe outer case may have exterior ornaments according to taste and requirements, and as it is not essential for setting forth thcinvention it is not shown in the drawings.

The frameAis made of steel or forged iron of triangular, square, or polygonal shape, and is carried in an upright position by means of pivots w and uf, constituting a vertical sh aft. The said pivots may be hollow for receiving the wires for the electric light. rlhe lower pivot 'w is prolonged and connected with a clock-work I by bevel-whecls u u?. The clockwork I would keep the frame in contin ual rotation if it were not stopped during certain intervals by a stopping device which can be disengaged, and is described hereinafter.

The shaft 9' of the clock-work I, carrying the bevel-wheel n2, is provided with a toothed wheel p, which gears with the pinion t, rotating loosely on the shaft 71,. lith the pinion lr is securely connected a lever d, which carries at the upper end the pin o and at the lower end a counter-weightg. This pin 0 stops the movement of the clock-work I as soon as the pin touches the projection r of a vibrating leverf, as seen by Figs. l and In this position the clock-movement I stops, and accordingly, also, the frame A. Then a rotating advance of the frame is to take place, the pin o must be released from the projection 'u of the lever f, this being done in the following manner. A second clock-movement II draws a toothed wheel y, on the circumference of which rests the tooth t' of a lever oo. The free end of the lever touches the lever f underneath and raises the latter as soon as the lever c is raised by the toothed Wheel y, which takes place upon the advance of each tooth of the wheel y. As soon as the lever x is raised completely, as shown by Fig. 4, the pin 0 moves from the projection t', and the former falls then against a second projection q, attached lower to the lever f. IVhen now upon further motion of the wheel p the lever o: falls again, the lever f falls also, and the pin o arrives over the projection q, when the clock-movement I can move, as now the lever (l is detained no longer. The lever d, with its motorpinion Z, makes nowa complete revolution in the direction of the arrow 2, Figs. 2 and 3, until the pin o, as shown by Fig. 3, arrives again on the projection o of the lever fand stops the clock-movement I. The second projection q on the lever f is of importance,because the same detains the arm d for so long, until the lever fhas descended so far that the projection t# catches the rotating pin o of the arm d on its return.

By regulating the cog-wheel p of the clockmovement I[ to advance by one tooth within a certain interval, one can regulate correspondingly the disengaging device, and thus the intermittent rotation of the frame A.

For fastening the advertisements to the frame, suitably large mounts K are used, to which are attached the sheets, pictures, the. 'lhese mounts are suspended on screw-pivots n, arranged above and below on the frame, and are kept by thumb-screws. The hook` bolts c serve for tensioning the sides of the frames, these being inserted into the mounts, as seen in Fig. 5, and kept and tightened in IOO the ribs ym of the frame by means of thumbserews. The ribs m are provided with proj eating cheeks at those places where the screwbolts are to be inserted, said cheeks being provided with holes for the bolts c. Instead of iron ribs, iron tubes may also be used.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

In apparatus for exhibiting advertisements, the combination of the frame A, an upright shaft therefor, a Clock-movement I for transmitting` rotary motion to said frame, an escapement consisting of a vibrating lever f,

ment-lever f, all snbstanthlly as herein dezo scribed.
